Optimal feeding via constrained processes

An organism’s optimal feeding rate is governed by constraints imposed by processes associated with consumption. In this paper a generic representation of feeding rates is derived based upon process constraints, and mechanistic representations of the module processes are illustrated for a filter feeder,Daphnia magna,and a pursuit feeder, rainbow trout (Oncorhynchus mykiss). The generic feeding rate models are presented in a spectrum of forms as dictated by process constraints and are convenient for application to a wide range of macroheterotrophic organisms.
